Find the Number of Moles of Air in Your
Classroom!
Determine the number of moles of air in your classroom using a meter stick, a
thermometer, and the current atmospheric pressure. Once you have done this,
determine the number of grams of gas that are in your classroom (the average
molar mass of air is approximately 29 g/mol).
During this activity, make sure that you use all of the correct conversion factors
and the correct value of the ideal gas constant. Show your measurements and
calculations in the space below. For simplicity’s sake, assume that there are no
solid objects within the room that take up space.
Good luck!
